Hi Thierry, everyone, You asked for review of your LCWDs from a POWDER perspective. IU've taken a look at both documents and don't have any substantive comments on either since they are some distance removed from what POWDER was designed to do (which is good because it means there's been no pointless duplication of effort!). The document that perhaps has most relevance is your Ontology for Media Resources. You might consider adding a short section in the manner that was done for mobileOK [1], or elsewhere in your group output, to show how a publisher can easily apply terms from the ontology to multiple resources. Recall that a key feature of POWDER is its ability to derive semantic meaning from URIs that are otherwise completely "dumb" from a machine's perspective. For example, a human would have no difficulty interpreting this URI http://example.com/movies/sci-fi/ as being the base for perhaps a whole catalogue of science fiction films. Specific URIs might then be: http://example.com/movies/sci-fi/alien.mpg http://example.com/movies/sci-fi/aliens.mpg http://example.com/movies/sci-fi/alient3.mpg http://example.com/movies/sci-fi/alienresurrection.wmv http://example.com/movies/sci-fi/bladerunner.mov A POWDER document could be constructed to make various assertions about these films available to Semantic Web clients> <?xml version="1.0"?> <powder xmlns="http://www.w3.org/2007/05/powder#" xmlns:ma="http://www.w3.org/ns/ma-ont#"> <attribution> <issuedby src="http://example.com/company.rdf#me" /> <issued>2007-12-14T00:00:00</issued> </attribution> <dr> <iriset> <includehosts>example.com</includehosts> <includepathstartswith>/movies/sci-fi/</includepathstartswith> </iriset> <descriptorset> <ma:genre src="http://example.com/ontology.rdf#sf /> <ma:publisher src="http://example.com/company.rdf#me" /> <displaytext>Movies in this section of the website are all in the science fiction genre</displaytext> <displayicon src="http://example.com/sf-icon.png" /> </descriptorset> </dr> </powder> You can add in further description resources to say things about all the Alien films, or all those that end in .mpg. Given this information a POWDER processor can return triples that describe specific URIs.
